JAMES FURLONG, OF ROCHESTER, NEW YORK CHURN-POWER.

SPECIFICATION forming part of Letters Patent No. 276,799, dated May 1, 1883.

Application filed March 9, 1883. (No model.)

.To all whom it may concern:

Be it known that I, JAMES M. FUR-LONG,01' Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Churn-Powers; and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, in which Fignrel is a. front elevation. Fig.2isarear elevation. Fig. 3 is a plan showing the spring and a portion of the driving-wheel. Fig. 4 is a section in line a: w of Fig. 2, enlarged. Fig.

5is a side elevation of the crank-wheel and its. connections, enlarged. Fig. 6 is a section in line 3 y of Fig. 1, enlarged.

My improvements relates to spring-powers for operating churns; and it consists in the construction and arrangement of parts hereinafter more fully described and claimed.

In the drawings, A shows a frame of any suitable construction, in which is mounted a churn, B, having an ordinary dasher driven by a dasher-rod, (J.

D is a shaft, on which is mounted a drivingwheel, E, a coiled spring, G, and a brakewheel, H. The spring is attached at one end to the frame, as shown at a, and the other end is attached to the shaft in the same way that a clock-spring is attached. The driving-wheel turns loosely on the shaft, and has at its outer end a crank, b, by which it is turned to wind up the spring. The shaft has on the outside of the wheel a ratchet, c, permanently attached to it, and the wheel has on its face a detent, d, which engages with the ratchet, and a spring,

which holds the detent into engagement. By turning the shaft backward by the crank the wheel will remain stationary, the detent sliding over the ratchet, and the spring will be wound up. The shaft, when released, will give forward motion to the wheel to drive the machinery in the same manner as in a clock.

I is a cross-shaft provided with pulleys g h. iis a band connecting driving-wheel E with the pulley g,- and k is a band connecting pulley h with a pulley, l, on an upper shaft, m, from which power is imparted to thedasherrod by a crank-wheel.

My improvement is as follows:

K is a crankwheel on the outer end of the shaft m, which overhangs the churn. This wheel is provided with a crank-pin, it, having a washer or roller, as shown in the side view, Fig. 5. o o are two bearings, which project beyond the crank-wheel. The upper one is attached to its standard by a screw, 12, so as to be removable. r is a guide-rod, which slides vertically up and down in said bearings, di rectly in front of the crank-wheel. The guiderod extends down and is attached to the top of the dasher-rod by a coupling, 8, which allows disconnection;

tis a cross-head attached fast to the guiderod, extending across the face of the crankwheel, and provided with a slot, u, on its inner face, extending whole length, open at the ends and receiving the crank-pin a. By turning the crank-wheel it will be seen that the crosshead will be carried up and down by the crankpin, which is allowed free movement in the long slot of the cross-head, and therefore reciprocating motion will be imparted to the dasher.

The brake-wheel H is fast to shaftD and revolves with it, and it is separated from the .springE by a vertical plate, j, through which the shaft runs.

L is a brake consisting of a bar pivoted at one end to the frame, so as to rise and fall, and provided at the other end with a concave pad, 12, which rests on top of the brake-wheel.

M is a spindle resting on top of the brake, its upper end havinga thread,w,whicn passes through a nut, e, and its top provided with a head, 2, by which it may be turned. By the use of this screw rod or spindle the brake may be set to bear more or less upon the brakewheel, and be retained-withoutattention from the operator,who can attend to other matters, and is not obliged to control the brake by a constant pressure of the hand. The screw enables him to set the pressure as desired, and to hold it there by the action of the screw alone.

Having described my invention, I claim In a churn-power, the combination of the spring, the driving-wheel, the pulley and band connections, the crank-wheel, the polish-rod,

the slotted cross-head, the brake-wheel, the

brake, and the screw-spindle bearing upon the brake, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
